Question

我最近一直在玩React，遇到了这个错误：

未捕获的TypeError：无法读取属性＆＃39; object＆＃39;未定义的 at Object.defineProperty.value（app.js：33843）在 webpack_require （app.js：20） at Object.defineProperty.value（app.js：33752）在 webpack_require （app.js：20）在对象。（app.js：5250）在 webpack_require （app.js：20）在app.js：63 在app.js：66

我注意到这与propTypes有关，在所有拥有它们的组件中都有。如果我从一个组件中删除propTypes块，则另一个组件会出现类似的错误。

Base.propTypes = {
  children: PropTypes.object.isRequired
};

我的package.json：

    "test": "echo \"Error: no test specified\" && exit 1",
